Burpee's "Eco-friendly" Organic Seed Starting Mix

[Greatgardens]

Has anyone else tried this? I bought a bag of it from Menard last month and was skeptical, because it is Coir, but the stuff seems quite good. It is a finer grind than their Coir pellets, but very, very uniform, and has zero "trash" (such as fine plates of bark and bits of rock and stems) that I find in most Peat seed starting mixes. There is a very tiny amount of what looks to be Perlite scattered here and there, but I would say less than 1% of the visible mix.

I set up a small comparison between Metro Mix, Burpee's coir, Jiffy Peat pellets, and Burpee's Coir pellets. Can see no differences thus far, other than both the pellets have a small edge in ease of use. But only three weeks since planting. Best germination was 4 days. "Worst" was 8 days. All but one seed had germinated by 6 days. Total germination was 94%.

Any other Coir mixes that folks have tried and like/dislike?
